SLIVER-HANDLING DEVICE.

Application filed February 6, 1922. Serial No. 534,445.

To all whom it may concern:

Be 1t known that 1, JOHN W. GURLEY, a citizen of the United btates,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Sliver-Handling Device, of which thefollowing is a specification.

In the manufacture of twine, the sisal or manila is first made into asliver on a spreader and then drawn into successively liner slivers bybeing passed successively through other Spreaders, draw frames, andfinishers until a sliver of the desired fineness is obtained. Heretoforethe sliver as it came from each of these machines has ordinarily beencoiled by hand in a can, the coiling of the sliver in the can requiringcon siderable skill; and the cans with the coiled sliver within themhave been carried from one machine to another, and used as fee cl cansover the edge of which the sliver was drawn when fed into the nextsucceeding machine. This scheme has not only required a great deal ofskilled labor, but has been disadvantageous also because of thediiiiculty of getting the sliver out of the can either for feeding orfor other reasons, and because of the cutting or tearing of the sliveras it passed over the edge ot'the can.

It is the object of my present invention to coil the sliverautomatically in a can, thus eliminating the necessity for the skilledlabor heretofore required for coiling it; and to coil it in such a wayin the can, and to make the can of such construction, that the coiledsliver may be removed laterally from the can and dragged independentlyof the can from one machine to another; so that the number of cans isreduced, one can to a machine being sufficient, and the diflicultiesinvolved in removing the sliver from the can are overcome. a

The accompanying drawings illustrate my invention: Fig. 1 is aperspective view of a can and sliver-feeding mechanism embodying myinvention, in connection with a draw-frame which is shown in dottedlines; Fig. 2 is a plan of the can and sliver-feeding mechanism whichfeeds sliver thereinto,

with a fragment of the associated draw frame; Fig. 3 is a sideelevation, in partial section, of the swinging feed chute; Fig. 4 is asection on the line 1-4 of Fig. 2; Fig. 5 is a section on the line 55 ofFig. 2; Fig. 6 is a Vertical section of the pivotal mounting on thesliver-receiving can; and Fig; 7

IS a plan of the can proper, showing the can open in full lines andclosed in dotted lines. The draw frame 9 shown in dotted lines 111 Fig.1 may be of any suitable construction, and is merely representative ofthe vallOIlS sliver-treating machines, such as Spreaders, draw frames,and finishers, with any of which my invention may be associ ated. Fromany of these machines, which takes the sliver and draws and works itinto a finer sliver in a well-understood man ner, such finer sliver 10is discharged at the end of the machine, the sliver as it-is dischargedpassing between two grooved delivery rollers 11 and 12 with which suchmachines are usually provided and which assist in drawing the sliverthrough the machine. These delivery rollers lland 12 are driven in anyconvenient manner by drive 'mechanism forming part of thesliver-treating machine, the roller 11 being shown as mounted on a shaft13 which is assumed to be so driven.

The sliver 10 is discharged into a can 15, embodying my invention, whichcan 15 takes the place of the cans heretofore used for receiving suchsliver. This can is mounted on a turn-table base 16 suitably mounted forrotation, as by having a pivot stud 17 mounted in a bearing socket 18set in the floor 19, as is clear from Fig. 6. The sides of the can aremade of two cylindrical segments 20 and 21, which project upward fromthe edge of the base 16. The segment 20 is fixed on the base 16, in anysuitable way, and the segment 21 is mounted on the segment 20on'vertical hinges 22 so that it may be swung to closed position asshown in Fig. 1 and in dotted lines in Fig. 7, to form a completecylindrical can, or to open position as shown in full lines in Fig. 7 toopen the side of the can for half its circumference. The opposite edgesof the seg ments 20 and 21 from those which are hinged together by thehinges 22 are preterably arranged to overlap, as indicated in Figs. 1and 7, and are provided with any suitable cooperating latch parts 23 forholding the segments in closed position. When the segment 21 is inclosed position, the sliver 10 maybe coiled within the can; but whenthe. segment 21 is swung open, the coiled sliver within the can mayeasily be slid out laterally onto the floor 19 and dragged to anydesired'place without moving the can. 7

, in a closed path.

The basel 6 and can 15 are driven in synchronis'm with the draw frame9or other-associated sliver-treating machine. Such driving isconveniently obtained by a belt which runs in a groov in the peripheryof the base 16 and passes over 'id'ler pulleys 26 to a driving pulley2-Ton any convenient moving shaft 28 of the draw frame 9. The

pulley 2'? is shown as on the sprocket shaft 28 of one of the drawingchains, though any other shaft may be used.

llhe sliver 10 is fed into the can by my automatic feeding device. Thisis fundamentally a swinging chute 30, which is shaped much like a cuppedhuman hand, and which is mounted to swing from side to side and up anddown in synchronism with the draw fran'i 9. To this end. the swingingchute 30 is made of curved cross-section, to evtend about half wayaround the sliver on its upper side. and is also curved longi tudinallyto direct the sliver downward, clear from Fig. 3. its rear end the chute30 is mounted by an upwardly projecting countersunl: pivot bolt 31 tothe lower end of a swivel cup 32 having a transverse hole 38 through itfor receiving the horizontal finger 3% f a standard 35 suitably mountedin a cross bar 36 at the discharge end of the draw frame 9. th swivelcup 32 being held from longitudinal movenzent along the linger 3% in anysuitable way, as by lying between a pair of cross-pins 3i projectingthrough such linger (Fig. 2). This makes a universal mounting for therear end of the swinging chute 30 so that it can swing up and downaround the axis of the finger 34 and can swing laterally around the axisof the pin-31.

Any suitable means may he provided for giving the chute 30 this doubleswinging n'ioveinent. so that its free end will travel is shown, thechute 30 is provided on its upper surface at its free end with upwardlyprojecting eye l0, through which loosely prcjeits a pin 41 on one end ofan arm 42. Said arm near its other end projects slidir I v through aswivel member 43 transversel. to the axis thereof, and such swivelmember 43 is swivtled on the u; oer end of a rod l which is verticallyadjustable to vary the l? at o the swivel member The, vertical.adjustircnt the rod 4% is convenicntl" obtained by having it projectthrough Jined holes in the legs of a suitably suppo; ted L -shapedmember so that a spring-pressed shoe 46 on the end of a pin l? project"thr'o h the base the Ushaped mem: e1 will bear aga nst the side of therod 44; hctwccirthe two ho es. through which it pa. and friction: llhold it'in ad of-the rod 1 .i. in Fig. 1, to provide an adjust nghandle. This provide? a vertically adjustable fulcrum point in which thearm 42 both swings extending linger 58, provided with a hole throughwhich projects an eccentric pin 49 carried by a disk 50 on a shaft 51suitably mounted in a bearing support 52 mounted on the cross bar 36.'At its other end the shaft 51 carries a friction disk 53 with the faceof which a friction roller 54'011 the shaft 13 cooperates. The roller'54 is preferably adjustable axially of the shatters, as indicated inFig. 2,'by such adjustment producing difi erent relative speeds ofrotation of the shafts 13 and 51.

In operation: The rollers 11 and 12 dis charge the sliver 1O beneath theswinging chute 36, which directs the sliver downward into the can 15.The chute 3O swings both on the axis of the finger 34 and on the aXis otthe pivot bolt 31., so that its free end travels in a closed path todirect the sliver 10 into the can 15 in the form of a coil. Thismovement of the swingingchute 30 is produced by the action of theeccentric pin 49, the rotation of which both sw'ingsthe arm 42 up anddown with the swivel member 43 as a fulcrum and slides such arm 42longitudinally back and forth in the swivel member 48. The swingingmovement of the chute 30 is of such extent that it makes a sliver-coilof less diameter-than the can '15, preferably about half such diameter,as is clear from Fig. 2. At the same time that the sliver is fed intothe'can 15, the can is slowly rotated, so thatzt'or each turn or coil ofthe sliver the can makes a fraction of a revolution; so that as a resultsuccessive turns or coils of. the sliver are not directly superposed,but instead are displaced circumferentially of the can. This makes anon-tangling coil. When the can 15 is full, the side segment 21 thereofmay be swung open and the sliver-coil within the can may be dragged outof the can onto thefloor 19, or onto a low truck, and slid on the flooror carried on the truck to the next machine or other desired place. Thenthe side segment 21 is closed again.. and another coil or sliver 10 isfed into the same can.
